I completely disagree with the other comments that say to only enter Box 2 on its own K-1, with nothing else, and the thought that all of the other boxes go on the 'other' K-1 with Box 1.
For the 'other' boxes, in most cases you need to know if that amount (or a split amount) applies to the Box 1 activity (usually non-passive) activity or if it applies to the Box 2 activity (usually passive).
For example, the K-1 could show some capital gains. You need to know if that applies to a non-passive situation (for example, selling some machinery that is used in the business activity), or if that applies to a passive situation (for example, selling a rental property).
